6.9 Recycle function if flame goes out during operation
The control box allows recycling, i.e. the complete repetition of
the start/up program. If after the safety time since the last recycle the flame does not
appear, the burner carries out a lockout.
6.10 Restart function following firing failure
The control box allows the start-up programme to be repeated,
making up to 3 attempts, if no flame is formed by the end of the
safety time. If the flame still fails to appear after the fourth ignition attempt, the
burner locks out at the end of the safety time.
6.11 Control of the motor rpm
Check of the motor operation if the rotation number per minimum
minute exceeds (900 rpm). If the motor does not exceed the number of minimum turns, it
stops after 20 seconds.
6.12 Control box reset (using built-in button)
To carry out the control box reset, proceed as follows:

Press and hold the reset button for 1-2 seconds.

In case the burner does not restart it is necessary to check if
the limit thermostat (
TL
) is closed.

Post-purging time:
Additional purging when the heat request is completed,

case of ignition failure.
